Keywords:  slurry, refractory, wax, molten, cast
Also known as the "lost wax method." This is a process where a wax part is repeatedly dipped with layers of ceramic material slurry. After many layers are applied, the entire part is baked at a very high temperature. The high temperature hardens the layers and melts out the wax, leaving a mold ready for casting. The metals most commonly cast are aluminum, steel, zinc and magnesium.
A casting process that uses a wax or thermoplastic pattern and is surrounded in a refractory slurry to form a mold. Once the refractory slurry is dry, the wax or plastic is melted out and the mold is formed. Molten metal is then poured in to fill the area that was previously filled with wax.
type of casting, also known as the lost-wax method, in which a wax model of the desired object (called an investment) would be made and surrounded by a plaster-like compound. The compound would harden and then be heated until the wax melted, leaving the imprinted shape in the mold
